The implementation of syncing unique and non-unique index depended on
index names which used to be different before because of that there's
tendency to incorrectly identify index.
This PR adds a separate util for checking if a column has index without
relying on naming convention. It just goes and checks if there's any
index with that column in it, hence far more reliable.
Caused by #15680
PS: This also fixes issue where columns having search + unique index were not dropped automatically.
